QuantRank500

A public record of stock predictions, settled by the market itself.

What it is

QuantRank500 is a free, open-source platform that records stock predictions before the market opens and settles them against actual exchange trade records. Every prediction is timestamped, immutable, and settled automatically. No one reports their own results.

Everyone competes with the same simulated stake: the $500 account.

The rules

Predictions	One per day. Long only.
Holding period	Three trading days, maximum.
Minimum target	5.5% above entry.
The $500 account	Everyone starts with the same stake.
Cutoff	8:00 PM ET the prior trading day.

How it works

Lock a prediction tonight. It becomes a limit order at tomorrow's open. The market fills it — or it expires unfilled. Both are recorded. Every evening, the platform replays the session's trade records and settles every open prediction. After 33 settled predictions, you appear on the scoreboard.

What it is not

No accounts required. No emails. No notifications. No ads. No data sales. A publicly auditable record. Nothing more.

Status: in development. The settlement engine is built and validated against real market history. Public beta opens when validation completes. The code will be open-sourced at launch.

A record of predictions, not investment advice. Settled against exchange trade records; actual execution prices may differ due to spread, commissions, and fill timing. QuantRank500 verifies predictions, not executions.
